Toss kale, apple, quinoa, oil, and cumin on pan. Season with salt and pepper. Season salmon liberally with salt and pepper on all sides and place on top of kale mixture.

Roast 7 to 10 minutes (the thicker your fillet, the longer it will take) for medium rare. If you like your salmon more well done, remove kale and apple mixture from pan after 10 minutes and cook salmon an additional 3 to 5 minutes.
